Abstract

This paper presents an enhanced stationary frame PI current regulator that uses feedback of the controller/ modulator transport delay to significantly improve both the controller performance and its robustness to variations in load parameters. An improved anti-windup saturation strategy is then proposed to further enhance the system performance. Matching simulation and experimental results demonstrate the controller´s superior transient and tracking performance compared to a standard PI implementation.
